"Researchers at Stanford and Princeton have succeeded in identifying 70% of web users by comparing their web-browsing history to publicly available information on social networks. The study "De-anonymizing Web Browsing Data with Social Networks" [PDF] found that it was possible to reattach identities to 374 sets of apparently anonymous browsing histories simply by following the connections between links shared on Twitter feeds and the likelihood that a user would favor personal recommendations over abstract web browsing."


What you discuss publicly can and often will be used against you.
